HENRY G. GILES, OF TROY NEW YORK.

nmmnaam No. 102.533, dated May 3, 1870.

Be it known that I HENRY G. GILES, of the city of Troy, county of Rensselaer and State of New York,

have invented certain Improvements in Cooking- Stoves, of which the following is a specification.

The first part of my invention consists in aiding combustion by a hot-air draught taken down through and under the cross-bars to the center, thence down the front side of the oven to the bottom of the-same, and admitted through a damper to the grate, and also on all sides of the fire-pot and through perforations in in the same, to inter-mix with and burn the gases.

The second-part of my inventionis a perforated cover for the stove made in .two parts, and so arranged tlat air for burning'the gas s maybe let on, or shut o I The third part of my invention relates to a watertank on the rear of the stove, for heating water and retaining it for culinary and other purposes;

7 Description of Drawings.

Figure '1 shows a cross-section of the stove through the center, from front to rear.

Figure 2, thetop.

Figure 3, the lid or cover, with perforations for gashnrning.

Figure 4, the back of stove with water-tank.

This stove may be made after the manner of what is known to the trade as a common square three-fined, or other cooking-stove, in which my invention is applied by forming the chamber H under the cross-bars of the stove-top, and connecting said chamber with the pip or flue E, reaching down through the top oven-plate, and thence connecting with the flue F,

leading down to the damper G, which opens said flue F into the chamber A.

In the top of the stove are several apertures, P, opening through into the chamber H.

Through the openings P air is drawndown'into the chamber H, thence downpipe E through flue F and damper G into the chamber A, whence it is admitted to the flue through the grate. The flues H, E and F, being very hot, the air becomes highly heated on its passage, and in this state is applied tothe fuel, thereby causing a quicker and more perfect combustion of the same. When this hot draught is used'Wit-h effect, the front of the stove should be closed.

In fig. 3, I show a cover for the stove made in two parts, with a large annular cavity s between the two,

and perforations in the lower part, for the purpose of throwing air in jets down upon the fuel, or uponthe rising gases from combustion of fuel, for igniting and utilizing the same.

The air is first admitted through the openings g. This may not be new, but one or more cups T are raised in the lower part, to. match and form a cover 'or stopper for the opening q, when the top to is turned around to the right point. The advantage of this is that, when the gases from bituminous or other fuel are spent, the air may be shut off, and the heat retained.

On the back of the stove is the reservoir 1%.. Underneath it is the chamber L, extending the whole width of the stove, forming a rest on the outer edge for the reservoir R, so that said chamber L is formed by the reservoir R, and the ogee-formed plate 10 on the back of stove, at one side of said chamber L, and next to the back of the stove is the damper V, the purpose of which is to open or close said chamber to the back-flue, and at the same time to divert the rising heat from the back flue to the chamber L, where, striking the bottom of water-tank R, it is passed-back to said back flue over the top side .of said damper, when said damper lies horizontally.

The general form of the plate 10' is of some importanee, as. in manufacturing it may be made so as to be detached from the stove for convenience and safety ll shipping.

It is common, in making low-oven cooking-stoves, to have two plates back'of the fire-box. 'One is called front oven-plate, the other back fireplate. Between these is avchamber-running parallel with the fire-box, with openings made at each end through the sides of the stove, to admit a circulation of air in said chamber. This circulation may be quickened, and a larger volume of air added to the downward flue F,-by an opening made through the front oven-plate into said flue F, thus bringing said air, through the means of said flue, to the fuel, to sustain combustion.

The chamber H, flues E F, and damper G, in combination with the. chamber A- and lire-pot B, as and or the purposes set forth.
